Runway vs HeyGen: Which Fits Your Team?

This applies to B2B marketing teams producing short marketing, social and enablement video in-house without a full production crew. Credit rates and model line-ups change often, so confirm the in-product credit cost before a large batch.

The Core Difference In Runway Vs HeyGen

Runway and HeyGen solve different video jobs, because Runway generates and edits footage shot by shot while HeyGen turns a written script into a presenter-led video with an avatar, a voice and translated versions, and 63% of video marketers have used AI video tools to create or edit marketing video according to Wyzowl's 2026 survey.

That figure was 51% in 2025. The same Wyzowl survey, of 266 marketers and consumers, found that 91% of businesses use video as a marketing tool. The question for most teams is no longer whether to use AI video, but which kind of tool fits the job in front of them.

Both tools sit under AI video generation, yet they answer different briefs. One builds the pictures. The other builds the person delivering the message.

Runway (documented): Gen-4.5 generates clips from text or an image. Aleph 2.0 edits existing video in context, so a change made on one frame carries through the shot. Act-Two transfers an actor's movement, speech and expression from a driving video onto a character.

HeyGen (documented): Stock avatars on Avatar III, IV and V read a script. A Digital Twin is built from your own footage. Video Agent turns a prompt into a finished video with script, visuals, voiceover and captions, and Speed Mode translates it into 175+ languages, accents and dialects.

The rule (judgement): A footage job goes to Runway. A presenter job goes to HeyGen.

The rest of this comparison holds both tools to the same marketing jobs, so the difference shows up in the work rather than in feature counts.

How We Compared Runway And HeyGen

This comparison sets Runway and HeyGen against the same marketing jobs (ad and social footage, presenter explainers, localisation and edits to existing footage) and marks each difference as documented by the vendor's own help centre or as Growth Tribune's judgement.

Five tools were considered. Runway and HeyGen are compared head to head. Synthesia, Adobe Firefly and InVideo are covered as alternatives, for teams whose main job sits between the two.

Every tool is held to the same criteria:

• Generation modes
• Editing control over generated and existing footage
• Output fit for ads and social, presenter explainers, localisation and training
• Credit meter, credit expiry and the cost of re-generating
• Consent and disclosure controls

Two labels run through the post. Documented marks a capability or rate that the vendor's documentation, help centre or changelog states. Judgement marks Growth Tribune's reasoning about fit, quality or trade-offs, drawn from those facts.

Capabilities and credit rates are as each vendor documents them, and vendors change both often. Comparisons written by a vendor are treated as that vendor's claims.

Runway Vs HeyGen Features Compared

Runway gives a marketing team control over the footage itself, since its Aleph 2.0 model edits one frame of an existing clip and carries the change through the shot, while HeyGen gives control over the script and scenes of an avatar video before and after its Video Agent generates the draft.

Generation Modes

Runway (documented): Gen-4.5 turns text or an image into video, billed per second of output. Act-Two animates a character image or video from a driving performance video, transferring movement, speech and expression, for clips of up to 30 seconds.

HeyGen (documented): Stock avatars come in three generations, Avatar III, IV and V. A Digital Twin is built from footage of a real person, with that person's consent video. Video Agent takes a prompt plus options for avatar, voice, length and orientation, and optional files such as slides, product images or a logo. It then generates the script, visuals, voiceovers and captions.

The practical split is simple. Runway starts from an image, a prompt or a clip and returns footage. HeyGen starts from words and returns a presenter delivering them.

Editing Control

Runway's editing works on the pixels. Aleph 2.0 supports changes to background, wardrobe or accessories, weather, season or time of day, relighting, object or subject replacement and restyling, with an optional motion prompt. Runway also runs as a panel inside Premiere Pro and After Effects, where Aleph 2 can restyle footage already on the timeline, and as a DaVinci Resolve plugin.

HeyGen's editing works on the script and the scenes. Video Agent pauses at a Review Script and Delivery step, where the script and scenes can be changed before the draft is generated. Changes after generation are requested in chat. AI Studio edits any video scene by scene, and Avatar IV adds control over when gestures happen and in what order.

Output Fit

Judgement: Runway output suits ad cut-downs, social hooks, product B-roll and restyled versions of footage a team has already shot. HeyGen output suits explainers, product updates, sales enablement videos and anything that needs the same face and voice across many versions or languages.

Teams weighing HeyGen against other presenter tools can use the AI avatar video tools comparison for the wider avatar field.

Runway For Generated Footage And Shot-Level Editing

Runway is built for teams whose deliverable is footage, with Gen-4.5 generating clips from text or images at 12 credits per second and Aleph 2.0 editing existing video, so a one-minute Gen-4.5 sequence draws 720 credits before any re-takes.

Runway now publishes its website and changelog under the runway.com domain, while its help centre keeps the runwayml name.

Verdict (judgement): Runway is the stronger choice when the deliverable is footage rather than a person talking to camera.

Generation modes (documented): Gen-4.5 turns text or an image into video at 12 credits per second, so a 5-second clip costs 60 credits and a 10-second clip 120. Act-Two animates a character from a driving performance video for up to 30 seconds, at 5 credits per second with a 3-second minimum, on the Standard plan or higher.

Editing control (documented): Aleph 2.0 carries a one-frame edit through the shot. Runway runs as a panel in Premiere Pro and After Effects and as a plugin in DaVinci Resolve. Runway's Agent can create and edit Brand Kits. A Team plan for small teams shares monthly credits across up to nine members, with 1TB of storage, comments and shared agent skills.

Output fit (judgement): Ad cut-downs, social hooks, product B-roll and restyled versions of shot footage. Teams comparing Runway with other footage generators can start from the best AI video generators for marketing teams.

Cost meter (documented): Credits are charged per second of output. A minute of Gen-4.5 footage draws 720 credits, and each 10-second generation draws 120 credits, so every re-take of a shot adds the same cost again.

Pricing: Runway's plans and prices are in the table below.

Limitation (documented): Monthly credits on the Standard, Pro and Unlimited plans expire on the billing date. A team that generates a shot several times pays the per-second rate for each generation.

Best fit (judgement): Creative and content teams with an editor who assembles shots on a timeline. Runway is not a fit for a team that needs a presenter reading a new script every week.

HeyGen For Presenter-Led Video, Avatars And Translation

HeyGen is built for presenter-led video, turning a script or a prompt into an avatar video and translating it in Speed Mode across 175+ languages, with Avatar IV drawing 16 credits per minute on a photo Look and 31 on a video Look.

Verdict (judgement): HeyGen is the stronger choice when the deliverable is a person talking to camera, produced at volume.

Generation modes (documented): Stock avatars run on Avatar III, IV and V. A Digital Twin is built from your own footage, with a consent video from the same person. Video Agent takes a prompt plus slides, product images or a logo and generates script, visuals, voiceover and captions.

Editing control (documented): Script and scenes can be edited at the Review Script and Delivery step before generation. Later changes are requested in chat. AI Studio edits scene by scene, with avatar looks and custom backgrounds, and Avatar IV controls when gestures happen and in what order.

Output fit (judgement): Explainers, product updates, sales enablement and localisation. Speed Mode translates into 175+ languages, accents and dialects. Precision Mode is video-aware, with better handling of occlusion and multiple speakers.

Cost meter (documented): Credits are charged per minute of output. Avatar IV draws 16 credits per minute on a photo Look and 31 on a video Look, against 7 and 4 for Avatar III. Avatar V draws 48, Custom Expressive Motion adds 40 on Avatar IV, Video Agent draws 80 (or 240 in Seedance mode) and translation 4 to 10.

Pricing: HeyGen's plans and prices are in the table below.

Limitation (documented): Plan credits cannot be used through Zapier or Make, which need a separate API key and API credits. Monthly credits carry into one extra billing cycle and then lapse, and HeyGen says credit rates and limits can vary by account.

Best fit (judgement): Marketing, sales and enablement teams that need the same presenter delivering new scripts often, or one video in many languages. HeyGen is not a fit for cinematic product footage or for changing footage a team has already shot.

Runway Vs HeyGen Pricing And Credit Costs

Runway and HeyGen credits cannot be compared one to one, because Runway charges Gen-4.5 footage at 12 credits per second while HeyGen charges Avatar IV output at 16 to 31 credits per minute, so the fair comparison is how many finished minutes each plan's monthly credits buy.

Plan prices for both tools are in the pricing tables in each tool's section above.

What One Finished Minute Draws

Each vendor's credit is its own unit. The table shows what one finished minute draws in that vendor's credits, not a price.

Act-Two clips run up to 30 seconds each, so a minute of Act-Two means at least two clips. To compare plans, divide each plan's monthly credits by the per-minute rate of the mode you will use most. That gives finished minutes per month, which is the number a budget can work with.

Credit Expiry

• Runway: Monthly credits on the Standard, Pro and Unlimited plans expire on the billing date. The Max and Team plans can roll over up to one month of unused credits. Purchased credits do not expire, and Runway spends monthly credits first, then rollover, then purchased.
• HeyGen: Monthly subscribers' unused credits carry into one extra billing cycle, up to about 60 days, while on a paid plan. Annual subscribers' allocations accumulate until renewal. Unused credits are forfeited when a paid plan is cancelled.

Re-Generation Cost

Iteration is where budgets slip. Runway charges each generation at its per-second rate, so five generations of a 10-second Gen-4.5 shot draw 600 credits for 10 seconds of usable footage. HeyGen says Video Agent changes are fastest and cheapest at the script review step, before the draft is generated, so the cheapest habit is approving the script first.

Add-Ons And Extra Credits

HeyGen's Business plan sells extra credits in 100-credit blocks at $5, with optional auto-reload. Zapier or Make automations need separate HeyGen API credits on top of plan credits. HeyGen also says rates and limits can vary by account, so check the in-product credit cost before a large batch.

Judgement: Price the job, not the plan. Estimate the finished minutes the team needs each month in its main mode, then check them against that plan's own monthly credits.

Can Runway Make Talking Avatar Videos?

Runway can make a character talk, since Act-Two transfers an actor's movement, speech and expression from a driving video onto a character for up to 30 seconds, but Runway's Lip Sync struggled with faces far from the camera in Tom's Guide's 2024 review, so script-led presenter video remains HeyGen's job.

Act-Two (documented): It animates a character image or video from a performance video. It costs 5 credits per second with a 3-second minimum and needs the Standard plan or higher.

Lip Sync (independent review): Runway's Lip Sync animates mouth, face and head movement to an audio clip and supports voice cloning through ElevenLabs. In Tom's Guide's review, it handled a face far from and turned away from the camera worst, animating only half the mouth, and also struggled with beards.

Judgement: Runway's documented tools centre on performances and footage. None of them works like HeyGen's Video Agent, which goes from a script to a finished presenter video with captions and translation.

The decision rule follows from that:

• A single hero character performance, driven by an actor, goes to Runway Act-Two.
• A repeatable presenter reading new scripts every week goes to HeyGen.

Can You Use Runway And HeyGen Together?

Runway and HeyGen work well together, because HeyGen produces the presenter segment while Runway supplies generated B-roll and runs as a panel inside Premiere Pro, After Effects and DaVinci Resolve, where an editor assembles both. The trade-off is two separate credit pools to budget and track.

A combined workflow for a product launch video looks like this:

• Approve the script at HeyGen's review step before generating the presenter segment
• Generate product B-roll or restyle existing product shots in Runway
• Bring both into Premiere Pro, After Effects or DaVinci Resolve with the Runway panel or plugin
• Track Runway and HeyGen credits as two separate budgets
• Record the vendor's consent video for any employee avatar before generation

There are two shortcuts, each with a trade-off.

HeyGen video assets (documented): HeyGen offers third-party video asset models inside its own credits. Seedance2 draws 60 credits per 720p video or 150 per 1080p video, and Veo3 draws 90 credits per video regardless of length. That covers a short B-roll clip without leaving HeyGen.

Runway models in Adobe Firefly (documented): Adobe Firefly hosts Runway Gen-4.5 and Runway Aleph 2.0 as partner models.

Access (judgement): A Creative Cloud team can likely reach Runway's models this way without a separate Runway account.

Judgement: The shortcuts suit occasional B-roll. A team producing footage every week will want Runway's own tools, including Act-Two, Brand Kits and the editor plugins, rather than a model hosted elsewhere.

Consent And Disclosure Rules For AI Video

Under the EU AI Act, deployers must disclose deepfake content to a person at first exposure from 2 August 2026, so a marketing team publishing an avatar of a real employee or a generated person in EU-facing video needs both the vendor's consent recording and a visible label.

EU AI Act Article 50 (regulator guidance): The European Commission's guidance says the disclosure must be noticeable and must not rely on embedded marking alone. Providers of generative systems must mark AI-generated or manipulated content in a machine-readable, detectable format. Article 50 applies from 2 August 2026, and systems placed on the market before then have until 2 December 2026 for the marking duty. Evidently artistic, creative, satirical or fictional works carry a lighter duty to disclose in an appropriate manner.

Vendors add their own consent controls:

• HeyGen: Every video-based Digital Twin needs a consent video from the same person shown in the footage, read exactly as written and under 30 seconds. The person can record it remotely by phone through a QR code, and rejections show on the avatar's card.
• Synthesia: Every Personal Avatar needs a live on-camera consent recording.
• Adobe Firefly: Outputs from the Firefly Video Model carry Content Credentials.

Judgement: For any employee avatar, collect a written release as well as the vendor's consent recording, because the recording covers the vendor's terms and the release covers your own. Label avatars and generated people in EU-facing ads at the point a viewer first sees them.

AI Video Platform Comparison With Synthesia, Firefly And InVideo

Three alternatives cover the jobs between Runway and HeyGen, with Synthesia aimed at training and enablement avatars, Adobe Firefly at Creative Cloud teams that want Adobe and partner models in one place, and InVideo at social video edited by an AI agent on a timeline.

Synthesia (judgement): Synthesia fits training video that has to live in a learning system, since it offers quizzes, branching and SCORM export for LMS delivery.

Adobe Firefly (judgement): Firefly does better than Runway for a team that already works in Creative Cloud and wants Runway's models next to Adobe's own, in one account.

InVideo (judgement): InVideo does better than either for a social team that needs many short variants and wants an agent to make the edits on a timeline it can take over.

Synthesia For Training And Enablement Video

Synthesia suits training and enablement teams, since it exports avatar videos as SCORM packages, adds quizzes and branching, and routes videos through Brand Kit approvals, with avatar video drawing about 100 credits per finished minute.

Verdict (judgement): Synthesia is the stronger choice for presenter video that ends up in an LMS.

Generation modes (documented): AI avatars and voiceovers in 140+ languages, dubbing of existing videos into 130+ languages with voice cloning and lip sync, and PowerPoint to video. Express-2 avatars, announced in September 2025, are full-body avatars that pair lip sync with hand and body gestures.

Editing control (documented): Brand Kit with roles, permissions and approval before videos go live, plus live collaboration. Interactive video adds calls to action, branching and quizzes, and videos publish as a link, an embed or a SCORM package.

Output fit (judgement): Onboarding, compliance training, product training and enablement libraries.

Cost meter (documented): Self-serve plans include 10 minutes of video, 3 survey responses and 500 credits a month as one shared balance. Avatar video draws about 100 credits per finished minute, AI dubbing 80 per minute with lip sync or 40 without, and the API 160 per minute.

Pricing: Synthesia's plans and prices are in the table below.

Limitation (documented): Credits do not roll over and reset on upgrade, and credits are recalculated for each new version generated.

Best fit (judgement): L&D and enablement teams publishing to an LMS. Synthesia is not a fit for generated product footage.

Adobe Firefly For Teams Already In Creative Cloud

Adobe Firefly gives Creative Cloud teams Runway's Gen-4.5 and Aleph 2.0 as partner models next to Adobe's own Firefly Video Model, though Adobe's commercially safe claim covers only its own model, which it trains on licensed and public domain content.

Verdict (judgement): Firefly is the stronger choice for a Creative Cloud team that wants several video models in one place.

Generation modes (documented): The Firefly Video Model generates video from text and images. Adobe says it trains Firefly only on content it has permission to use, such as licensed Adobe Stock and public domain content, and never on customer content. Partner video models include Runway Gen-4.5, Runway Aleph 2.0, Google Veo 3.1, Luma Ray3 variants, Kling and Dreamina Seedance 2.0, with Kling and Seedance limited to individual plans.

Editing control (documented): The Firefly video editor can remove backgrounds from video and record voiceovers in the timeline. Auto reframe, the new generation and editing experience and enhance audio are in beta.

Output fit (judgement): Campaign footage and edits for teams already finishing work in Adobe tools, with Content Credentials attached to Firefly Video Model output.

Cost meter (documented): Partner video models draw generative credits per second of output, and the rate varies by model, resolution and audio.

Pricing: Adobe Firefly's plans and prices are in the table below.

Limitation (documented): Adobe's commercially safe claim applies to its own Firefly models. Adobe states that partner models are not developed by Adobe and that the user decides whether they are suitable.

Best fit (judgement): Design and brand teams living in Creative Cloud. Firefly is not a fit for scripted presenter video.

InVideo For Fast, Agent-Edited Social Video

InVideo suits teams producing many short social variants, because its Agent Two edits video from plain-language instructions on a multitrack timeline and charges generative video at 0.33 credits per second without AI actors and 0.67 with them.

Verdict (judgement): InVideo is the stronger choice for volume social video where speed matters more than shot-level control.

Generation modes (documented): Video models including Google Veo 3.1, Sora 2 and Kling run inside one product. InVideo v4.0, released in June 2025, added Personal AI Twins from a short recorded clip with video creation in 50+ languages, Product and Brand Twins from a product link or photos, and an AI Actor Library.

Editing control (documented): Agent Two carries out edits described in everyday language on a multitrack timeline, and the user can take over at any frame. Teams can also bring their own agents to edit on the timeline.

Output fit (judgement): Short ads, UGC-style clips and social cut-downs in many variants.

Cost meter (documented): Credits are charged at creation by video length. Generative video draws 0.67 credits per second with AI actors and 0.33 without. Stock-media video draws 0.5 credits per minute with your own AI Twin or no avatar, and 5 per minute with UGC actors.

Pricing: InVideo's plans and prices are in the table below.

Limitation (documented): Remix edits such as regenerating media, adding chapters or changing duration use plugin rates, for example 0.22 credits for one image and 1.67 for a 5-second clip.

Best fit (judgement): Social and performance teams producing many short variants. InVideo is not a fit for LMS-bound training.

Runway Or HeyGen For Marketing Videos?

Choose Runway when the marketing deliverable is footage you generate or edit, such as ad cut-downs and product B-roll, and choose HeyGen when it is a presenter reading a script, especially one you need in several languages. Teams that make both kinds of video can run both tools, with an editor joining the two outputs.
